Electric gear selecting and shifting executing mechanism

Abstract

The invention discloses an electric gear selecting and shifting executing mechanism. The mechanism comprises a gear selecting mechanism, a gear engaging mechanism, a self-locking mechanism, an interlocking mechanism, a transmission shaft and a shell; the gear selecting mechanism is arranged at one end of the shell; the gear engaging mechanism is arranged at the other end of the shell; the output end of the gear selecting mechanism is connected with a transmission body; the output end of the gear selecting mechanism is connected with the output end of the gear selecting mechanism through the transmission shaft; the self-locking mechanism is connected with the output end of the gear selecting mechanism and is used for preventing a transmission from undergoing spontaneous out-of-gear; and theinterlocking mechanism is connected with the output end of the gear selecting mechanism and is used for preventing the transmission from being engaged with multiple gears at the same time. Accordingto the electric gear selecting and shifting executing mechanism of the invention, the self-locking mechanism is adopted, so that the locking of a certain gear of the transmission is achieved, and therefore, the automatic gear jumping of the transmission caused by vibration in the running process of a vehicle is prevented; and the interlocking mechanism is adopted, so that the transmission can be prevented from being engaged with multiple gears at the same time, and therefore, damage to the transmission caused by such a condition is effectively avoided. The mechanism is simple in structure andcan assist inn decreasing the fault points of the transmission and improving the reliability of the vehicle.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to an electric gear selection actuator. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements for automobiles. On the premise of meeting the practical performance, it is more and more important to reduce driver fatigue, improve vehicle reliability, more convenient fleet management and use costs. more attention. In the field of medium and light trucks, electric vehicles and hybrid vehicles, the use of electric gear shifting has become a trend, which greatly simplifies the layout of the vehicle and saves costs. [0003] At present, none of the electric gear selection and shifting actuators on the market are designed with self-locking and interlocking structures. If the transmission does not have self-locking and interlocking devices, when the vehicle vibrates during driving, it is prone to automatic gear ...
